Antioxidant-Free Radical Scavenging of Some Euphorbiaceae Herbs

Titik Sunarni, Fransiska Leviana

Abstract


In order to screen natural antioxidant, the research about antioxidant of some Euphobiaceae herbs, have been conducted. The air-dried herbs  of Euphorbia heterophylla L, Phyllanthus acidus (L.) Skeels, and Phyllanthus buxifolius Muell Arg were extracted with metanol. The obtained extract was concentrated and then suspended to produce n-hexane, ethyl acetat and aqueous fractions. Free radical scavenger activity against DPPH (1,1-diphenyl-2-pycrylhydrazyl) measured by spectrophotometric method  and the IC50 value was determined. The compounds of  active fraction had been identified by TLC method. All of the herbs showed activity as DPPH scavenger. Among these herbs, Euphorbia heterophylla L. and Phyllanthus buxifolius Muell, Arg. exhibited a strong free radical scavenging of ethyl acetat fraction with IC50 value 5,88 µg/ml and 4,64 µg/ml. The result of TLC by mobile phase n-buthanol-acetic acid-water (4:1:5) and acetic acid 15% showed flavonoid compound.

Keywords: Euphorbiaceae herbs, antioxidant, DPPH, flavonoid
